Easy to operate
The TRI is a powerful tuning aid that, together with the automatically controlled input attenuator, helps the operator to quickly and precisely match the antenna impedance to the optimum tube load
impedance (5-10 seconds typically). The auto-operate function (when enabled) maintains the amplifier in the OPERATE mode for you, thus avoiding unnecessary manual operations.

No antenna tunersNo heavy outboard antenna tuners required for antenna VSWRs up to about 3:1. Your amplifier will enable you to change antennas
virtually instantaneously and allow you to use your antennas over wider frequency ranges.

User-friendlyAn amplifier that is both user-friendly and that looks after itself. It is
designed to safely withstand up to 300W reflected power, up to 100 milliseconds duration of drive spikes, drive RF tails” after a PTT or KEY release, operator’s inadvertent tuning
errors etc. The amplifier also will not cease to function with a “soft” AC mains and will deliver more than half power at only 85% of nominal mains voltage. It can withstand
voltage drops (down to zero Volts) for up to 10 milliseconds and can tolerate 15% mains voltage spikes, which is especially important on Field Day, during DXpeditions, and at portable operating
events where emergency power is relied upon.

Three antenna outputsThree antenna outputs are selectable using a push-button on the front panel.

Easy maintenanceData regarding amplifier internal status is stored in a nonvolatile memory for 7 of the most recent auto protection
trips. This information can be forwarded to your dealer for diagnostics.
